A Major Tornado Outbreak is forecast later today and tonight over portions of the Mid-Mississippi and Lower Ohio Valleys.

This is the same storm that yesterday produced 48 tornado reports, softball-sized hail, 80+ mph winds and at least 13 casualties across Kansas, Oklahoma and Northern Texas.

This is already a Particularly Dangerous Situation Tornado Watch issued for Southern Illinois, Southern Indiana, Western and Central Kentucky and Eastern Missouri. Violent tornadoes, hail to 3 inches in diameter, wind gusts to 70 mph and dangerous lightning are possible.

If you live in these areas, make sure your weather radio is turned on and working. If you don't have a weather radio, keep your radio or TV tuned to a local news station or monitor your local radar via the NWS web site or another weather site such as Weather Underground.

Yeah, that sounds like one of the older designs. The newer radios with Specific Area Message Encoding (SAME) are a lot more useful. Once programmed, it'll only go off if there's an alert within your county and will ignore everywhere else.
